The best time to take probiotics for infants and children is half an hour after meals, and it can be taken with warm water or orally in milk, and the water temperature should not exceed 40℃. Probiotics can regulate the body’s immune system, regulate the dysbiosis of intestinal flora, inhibit intestinal inflammation, relieve diarrhea and constipation, and reduce the occurrence of allergic diseases.

After meals, the concentration of stomach acid decreases, and it is more beneficial to let the live bacteria reach the intestine smoothly and take effect after using probiotics. Probiotics should not be taken at the same time as antibiotics, but at least 1-2 hours between the two. Some infants and children’s tummy rumbles after taking probiotics, this is a normal physiological phenomenon, no need to worry too much. However, young children should avoid oily food when taking probiotics orally, and pay more attention to the diet and choose foods with high dietary fiber content.
